Maybe because it had changed in the past? One can understand why one could mark it "text" in the first place as it is a text based browser not realizing that text is "for text processors". But in 0.5.2-3 it had the change of "Set Section to web." That version is old (pre-precise), so it has been that way (web) for quite some time. Therefore when you check the sources "web" is what you get just as with the /var/lib/dpkg/status check mentioned above. $ apt source w3m $ grep Section w3m-0.5.3/debian/control Section: web Also it is Section web on lauchpad for example at https://launchpad.net/ubuntu/+source/w3m/0.5.3-37 But OTOH the cache data is on "text" - and that is what apt/synaptic will use: $ apt-cache show w3m | grep Section Section: text It seems some data holds to the old "text" entry ever since. Overview: web: /var/lib/dpkg/status, launchpad, source text: apt-cache, synaptic Is there a step needed/missed to make the apt/repository data refresh the section? > -- > Gunnar Hjalmarsson > https://launchpad.net/~gunnarhj > > -- > Ubuntu-devel-discuss mailing list > Ubuntu-devel-discuss@lists.ubuntu.com > Modify settings or unsubscribe at: > https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss -- Christian Ehrhardt Staff Engineer, Ubuntu Server Canonical Ltd -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss

Re: [users@httpd] Fwd: apache2 / httpd graceful/reload failures on Ubuntu 21.04
Reading the source code:
From mod_slotmem_shm:
...
401 apr_shm_remove(fname, pool);
402 rv = apr_shm_create(&shm, size, fname, gpool);

411 fbased && is_child_process() ? "attach" : "create",
412 fname, rv == APR_SUCCESS ? "succeeded" : "failed");
Autoconf defines APR_USE_SHMEM_SHMGET for SHM namebased memory allocation
...

381SHM_R | SHM_W | IPC_CREAT | IPC_EXCL)) <
0) {
382 apr_file_close(file);
383 return errno;
384 }
From shmget() manual page, possible errors in errno:
ENOSPC: All possible shared memory IDs have been taken (SHMMNI), or
allocating a segment of the requested size would cause the system to exceed
the system-wide limit on shared memory (SHMALL).
So your "No space left on device" is not on your filesystem but on your shared
memory sysv.
Since SHMALL on a 64bit linux system is very big (please try this: cat
/proc/sys/kernel/shmall), I would bet on a low SHMMNI value on your system
(pls: cat /proc/sys/kernel/shmmni)
SHMMNI is the global maximum number of shared memory segments on your system.
Default on Ubuntu should be 4096. Please try to increase the value (echo 8192 >
/proc/sys/kernel/shmmni) or more.
HTH.
Ciao, Dino.

apache2 / httpd graceful/reload failures on Ubuntu 21.04
Hi, I've been experiencing a failed apache2 service on Ubuntu 21.04 when performing a reload using the `systemctl reload apache2` command. The command does not always fail, but seems to be failing more often as the number of vhosts increases (currently ca 120). My The `systemctl reload apache2` command exits without error, but the service ends up in a failed state. Running `systemctl start apache2` after this failure starts the service without issues. I had taken to do running `systemctl reload apache2; systemctl status apache2` to validate that I have a running service, but this would report "success" even when the service is "failed". Expecting some timing issue, I increased the "RestartSec" systemd parameter to 500ms using `/etc/systemd/system/apache2.service.d/override.conf` [Service] RestartSec=500ms This has not fixed the issue either. Testing the reload using `apachectl -k graceful` can also trigger the "failed" state of the process. The consistent error is with the persistence of shared memory segments. The indicated error is incorrect, there's plenty of space on the filesystem. The configuration has been kept as close as possible to the default Ubuntu config. My gut feeling is some weird interaction between graceful and systemd as seen in the logs. The RestartSec change not solving the problem kind of goes against that. Any help appreciated!

Misplaced packages?
Greetings Ubuntu Developers! I was just browsing some sections in Synaptic, looking for lightweight webbrowsers and image gallery creation. During my browse I found some strange package placements: w3m, a text based webbrowser, is placed in the section Word Processing bluefish, a text editor, is placed in World Wide Web (multiverse) florence, a virtual keyboard for X, is placed in World Wide Web (multiverse) All on Ubuntu 20.04(.3). -- Kind Regards, Robert Spanjaard -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
